We performed sentiment analysis by VADER and proposed a new method that can count the individual's influence.
The results indicated that celebrities could lead the opinion shift on social media in vaccination progress.

- Abstract: Social media is an appropriate source for analyzing public attitudes towards
the COVID-19 vaccine and various brands. Nevertheless, there are few relevant
studies. In the research, we collected tweet posts by the UK and US residents
from the Twitter API during the pandemic and designed experiments to answer
three main questions concerning vaccination. To get the dominant sentiment of
the civics, we performed sentiment analysis by VADER and proposed a new method
that can count the individual's influence. This allows us to go a step further
in sentiment analysis and explain some of the fluctuations in the data
changing. The results indicated that celebrities could lead the opinion shift
on social media in vaccination progress. Moreover, at the peak, nearly 40\% of
the population in both countries have a negative attitude towards COVID-19
vaccines. Besides, we investigated how people's opinions toward different
vaccine brands are. We found that the Pfizer vaccine enjoys the most popular
among people. By applying the sentiment analysis tool, we discovered most
people hold positive views toward the COVID-19 vaccine manufactured by most
brands. In the end, we carried out topic modelling by using the LDA model. We
found residents in the two countries are willing to share their views and
feelings concerning the vaccine. Several death cases have occurred after
vaccination. Due to these negative events, US residents are more worried about
the side effects and safety of the vaccine.

With the rollout of vaccination campaigns, German-speaking regions exhibited much lower vaccination uptake than other European regions.
We show that skepticism regarding the severity of the COVID-19 virus and towards efficacy and safety of vaccines were among the prevalent topics in the discourse on Twitter.
During later phases of the pandemic, when implemented policies restricted the freedom of unvaccinated citizens, increased vaccination uptake could be observed.

Administering COVID-19 vaccines at a societal scale has been deemed as the most appropriate way to defend against the COVID-19 pandemic.
This global vaccination drive naturally fueled a possibility of Pro-Vaxxers and Anti-Vaxxers strongly expressing their supports and concerns regarding the vaccines on social media platforms.
The goal of this work is to improve this understanding using the lens of Twitter-discourse data.

Early analyses revealed that dark web marketplaces (DWMs) started offering COVID-19 related products (e.g., masks and COVID-19 tests) as soon as the COVID-19 pandemic started.
Here, we broaden the scope and depth of previous investigations by analysing 194 DWMs until July 2021, including the crucial period in which vaccines became available.
We show that recreational drugs are the most affected among traditional DWMs product, with COVID-19 mentions steadily increasing since March 2020.

We examine the extent to which the vaccination debate on Twitter is conductive to potential outreach to the vaccination hesitant.
We discover that the vaccination skeptics, as well as the advocates, reside in their own distinct "echo chambers"
At the center of these echo chambers we find the ardent supporters, for which we build highly accurate network- and content-based classifiers.
